What is Sandbox Inspection?
Sandbox inspection is a network process that allows files to be sent to a separate device, such as FortiSandbox, to be inspected without risking network security. This allows the detection of threats which may bypass other security measures, including zero-day threats.
You can configure your FortiGate device to send suspicious files to FortiSandbox for inspection and analysis. The FortiGate queries scan results and retrieves scan details. The FortiGate can also download malware packages as a complimentary AV signature database to block future appearances of the same malware and download URL packages as complimentary web filtering black list.
When a FortiGate sends files for sandbox inspection, the FortiSandbox uses virtual machines (VMs) running different operating systems to test the file and to determine if it is malicious. If the file exhibits risky behavior, or is found to contain a virus, a new signature can be added to the FortiGuard AntiVirus signature database.
When a FortiGate learns from FortiSandbox that a terminal is infected, the administrator can push instruction for self-quarantine on a registered FortiClient host.
FortiSandbox can process multiple files simultaneously since the FortiSandbox has a VM pool. The time to process a file depends on hardware and the number of sandbox VMs used to scan the file. It can take 60 seconds to five minutes to process a file.
